Ah, through

> [@VTK CMake Usage](https://discourse.vtk.org/t/vtk-cmake-usage/3275):

> How does one find and use VTK in CMake with 9.0.0. I’m using find\_package(VTK REQUIRED …), and it’s seems happy, although the only output appears to be finding X11 and Xt. All the documentation that I can find is conflicting, and appears to be outdated. I would appreciate it if someone could point me to up-to-date documentation or an example. I just need to know what variable to use to get the include/library paths, and libraries.

I came to this:  
[https://gitlab.kitware.com/vtk/vtk/-/blob/1abfe43a7b32b4606964005627b6c40723883a2e/Documentation/Doxygen/ModuleMigration.md](https://gitlab.kitware.com/vtk/vtk/-/blob/1abfe43a7b32b4606964005627b6c40723883a2e/Documentation/Doxygen/ModuleMigration.md)  
and it seems indeed there are some additional steps required. I’ll try that and report back my findings!
